To turn our short- into a long-block, we turned to the Edelbrock Performer RPM line. Good for maximum power from 1,500 to 6,500 rpm--we figured massive displacement would substitute below 1,500 rpm--Edelbrock's power package starts with a camshaft and lifter kit (PN 7157) and a roller timing set (PN 7812). The Performer RPM cam has an advertised duration of 290 degrees intake and 300 degrees exhaust along with a 0.556-inch lift intake and a 0.581-inch lift exhaust.
